A team of scientists proved that seals had a very good sense of hearing．These men trained blind seals to expect food when they heard sounds．The seals always began snapping(猛咬)when a strong signal was sounded．
It was proved that even a soft signal, a considerable distance away, could make these sea animals respond．That should make the fisherman who makes much noise while working, or talks loudly, start thinking．
The same team of scientists also trained seals to recognize different sounds．One bell-tone meant food, two bell-tones meant no food．In the beginning, the seals made mistakes when the two bell-tones were sounded．They were given a light tap after each mistake．The seals were good learners．They easily learned to tell the difference between the sounds．
(1)
Why was it necessary to use blind seals?Because they ________．
[ ]
A．
were unable to use sight for clues
B．
had better hearing
C．
were waiting to be fed
D．
were the only animals to be found
(2)
To those seals strong signal meant ________．
[ ]
A．
snapping
B．
nothing
C．
food
D．
a light tap
(3)
The article doesn't say directly but suggests that fishermen usually think ________．
So far, scientists have named about 1.8 million living species(物种), and that’s just a small part of what probably exists on Earth．With so many plants, animals, fungi, and other organisms covering the planet, it can be tough to figure out what type of spider is crawling up your leg or what kind of bird just flew by．
A soon-to-be-launched Website might help．An international team of researchers has announced the creation of a Web－based Encyclopedia of Life(EOL)．The project aims to catalogue every species on Earth in a single, easy-to-use reference guide．
To get the encyclopedia started, the creators will use information from scientific databases that already exist．And eventually, in special sections of the site, nonscientists with specialized knowledge will join．Gardeners, for example, will be able to record the dates that their flowers first bloom each year．Bird-watchers will be able to input which birds they’ve seen and where．The technology for this kind of tool has only recently become available．
As the EOL develops, you might find it useful for school projects．The site will have special pages for kids who are studying ecosystems in their neighborhoods．To make sure the encyclopedia is accurate, scientists will review much of the information added to it．People who visit the site will be able to choose to skip pages that haven’t been reviewed．
Another convenient characteristic of the EOL is that you’ll be able to pick the level of detail you see to match your interests, age, and current knowledge．If you wanted to learn about polar bears for a science class report, for example, you could use the“novice”setting to get basic information about the animals．On the“expert”setting, on the other hand．you could get much more detailed information about the history, literature, and exploration of polar bears．
It now takes years for scientists to collect all the data they need to describe and analyze species．The creators of the Encyclopedia of Life hope that their new tool will speed that process．
Keep an eye on www.eol.org．Pages will begin to go up sometime next year, and you might find them useful for your school reports．The EOL team might have the basics for all 1.8 million entries online as early as 2017．Someday, you might add your own notes．

Watching 3D films such as Avatar could give some viewers headaches, experts have warned．
The success of James Cameron's science-fiction blockbuster(卖座的大片), which has already taken more than ＄1 billion(￡600 million)at the box office, is fuelling a surge in popularity for three-dimensional movies and new 3D television sets．
But prolonged viewing may result in an aching head, according to Dr Michael Rosenberg, an ophthalmology(眼科学)professor at Northwestern University Feinberg School of Medicine in Chicago．
He said："There are a lot of people walking around with very minor eye problems, for example a minor muscle imbalance, which under normal circumstances the brain deals with naturally．"
Watching a 3D movie confronts viewers with an entirely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," he said．
Dr Deborah Friedman, a professor of ophthalmology and neurology(神经学)at the University of Rochester Medical Center in New York, said："If your eyes are a little off to begin with then it's really throwing a whole degree of effort that your brain now needs to exert．This disparity for some people will give them a headache．"
Experts say there are no studies tracking how common it is to get a headache after watching a 3D film．
Rick Heineman, a spokesman for RealD, which provides 3D equipment to cinemas, said headaches and nausea were the main reasons 3D technology never took off before．
But he said new digital technology addresses many of the problems that had previously caused sore heads．
(1)
What can we learn from what Dr Michael Rosenberg said?
[ ]
A．
A lot of people prefer walking around with very minor eye problems to sitting silently watching 3D films．
B．
The brain can deal with very minor eye problems under normal circumstances naturally．
C．
A lot of people haven’t got very minor eye problems when viewing films under normal circumstances．
D．
People come into very minor eye problems and a minor muscle imbalance when watching 3D films．
(2)

Once upon a time the colors of the world started to quarrel．Green said,“Clearly I am the most important．I am the sign of life and hope．I was chosen for grass, trees and leaves．Without me, all animals would 1 ．”
Blue interrupted,“You only think about the 2 , but consider the sky and the sea． 3 the water that is the basis of life and drawn up by the clouds from the deep sea．Without my peace, you would all be 4 ．”
Yellow chuckled(笑道),“You are all so serious．I bring laughter, fun, and 5 into the world．”
Orange started next to blow her trumpet,“I am the color of health and strength．I may be 6 , but I am precious for I serve the needs of human life．When I fill the sky 7 , my beauty is so striking that no one gives another 8 to any of you．”
Red could stand it 9 and he shouted out,“I am the ruler of all of you．I am the color of danger and of bravery．I am willing to 10 truth．I am also the color of passion and of love．”
Then came Purple and Indigo(深蓝)…．
The colors went on boasting, each convinced of his or her own 11 ．Their quarreling became louder and louder．Suddenly there was a startling flash of bright lightening thunder．Rain started to pour down 12 ．The colors crouched(蜷缩)down 13 , drawing close to one another for comfort．
In the midst of the clamor(叫嚷), rain began to speak,“You foolish colors, fighting 14 yourselves, each trying to dominate 15 ．Don't you know that you were each made for a special purpose, 16 ?Join hands with 17 and come to me．”
Doing as they were told, the colors 18 and joined hands．They formed a colorful rainbow．From then on, whenever a good rain 19 the world, a rainbow appears in the sky．They remember to 20 one another．
